IMPROVEM ENT IN WIND-ENGINES.

Specification forming part of Letters Patent No. 208,841, dated October 8, 1878; application iled March 20, 1878.

To all whom 'it may concern:

Be it known that I, OHARLEs E. MYERS, of Schoolcraft, in the county of Kalamazoo, and State of Michigan, have invented a new and valuable Improvement in Windmills; and I do hereby declare that the following` is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a rear view of my wind-mill, and Fig. 2 is a part sectional side View thereof.

My invention relates to windmills; and it consists in the construction and arrangement of the devices for throwing the mill out of gear 5 and also in combining therewith, to be operated thereby, a brake, and in the construe tion of such brake, all as hereinafter more fully set forth.

The annexed drawing, to which reference is made, fully illustrates my invention.

A represents the mast of the wind-mill, with cap-plate B at the top, and a step, C, a suitable distance below said cap-plate. The turntable is composed of a hollow tapering tube, D, passing through the cap-plate B, and its lower smaller end resting in the step C. At the upper end of the tube D are formed two arms, Dl and D2. The arm Dl forms a bearing for the shaft a, and over the saine is placed a cap, E. On the outer end of the shaft a is secured the wind-wheel F, and the inner end is provided with a crank, b, which works in a slotted head in the upper end of the rod G, said rod passing down through the tube D to the pump or other machinery to be driven.

0n the arm D2 of the turn-table is secured a frame, H, in suitable bearings upon which is placed a horizontal shaft, I, running at right angles to the wind-wheel shaft. This shaft I is at one end provided with the vane J, for throwing` the wheel out of gear.

To the frame H is secured an outwardly-projecting forked arm, K, in which is pivoted a lever, L, said lever being omits upper end provided with an inclined vane, L1. The lower end of the lever L is curved, as shown, and upon the same is placed a movable or adjustable weight, L2. The upper portion of the lever L is, by a pivoted rod, d, connected with an arm, c, on the shaft I.

When the wheel is in gear the main vane J lies horizontal, and the wind strikes the vane LI before it strikes the wheel F. As long as the force of the wind does not overbalanee the weight L2, the wheel remains in gear or in the wind 5 but as soon as the force of the wind on the vane L1 overbalances the weight L2, said vane L1 is turned forward, and, by its connection with the shaft I, turns said shaft so as to bring the vane J against the wind, and the wheel is then turned out of gear or out of the wind. As soon as the wind decreases again the weight L2 turns the shaft I and vane J to their former position, and the wind throws the wheel around in gear again. But should the wind not be strong` enough to turn the wheel to the wind, as sometimes happens, the operator can turn the wheel in the wind by means of a wire, chain, or cord, f, attached to the main vane J, and having a small weight, h, attached toits lower end. This weight and wire in nowise interfere with the automatic movement of the said vane.

It is obvious that, in using the cord f for the purpose above mentioned, it must be passed over the vane from the front side, and be suspended from the rear side next the wheel. The operator thereby secures a leverage from both wings of the vane, and is enabled to move the same with great ease.

On the shaft I is secured or formed a cam, m, which is to operate against the weighted end of a lever, It, which is pivoted between two standards, S S, rising from the cap E, or any suitable part of the turn-table. 0n the inner end of the lever It is secured a brakeshoe, a, which is to act upon a ring, p, secured on the inner side of the wheel F.

WV hen the shaft I is turned, as above described, for throwing the wheel out of the wind, the cam m raises the outer weighted end of the lever It and presses the brake a onto the ring p with a pressure corresponding to the amount of pressure on the vane L1, so as to stop the revolution of the wheel, which is many times of great importance, as the mo lnentum of the wheel already acquired would keep it in motion for some time and might cause serious accidents. By the automatic application oi' a brake operated by the means i 2. 1n a windmill, the combination, with the for throwing the wheel out of' the wind this is l Wind-wheel and the devices for throwing the entirely obviated. same in and out of gear by the act-ion ot' the The operator can stop the lnill at any time wind, of an automatic brake applied to the from the ground by means ot' a wire, cord, or Wheel by the said devices for throwing the chain, f, oonneeted to an arm. s, on the shaft i wheel in and out of' gear, as herein set forth.
